A super sexy rendition of Marceline from Adventure Time!
I actually used a stock image for this one.
Here is the stock photo I used. This lovely lady is the model and photographer. She deserves all the wonderful credit I can give to her ♥[link]
I only used her face and top portion from this photo, but I think I did an alright job of giving it a darker feel.
Here are more Adventure Time characters:
Princess Bubblegum: [link]
Flame Princess: [link]
Lumpy Space Princess: (coming soon?...Maybe)
